STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Fatent No. 781,263, dated January 31, 1905.

Application filed .pril '7, 1904. Serial No. 201,988.

To all whom, it may concern:

Be it known that I, OLOF ANDEnsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stem Vinding and Setting Watches, of which the following is a specification.

This invention relates to improvements in a winding and setting mechanism of the pendent type for that class of watches known to the trade as the American style of watchcasesthat is, such cases as have fitted therein the pendent sleeve and stem; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a pendent set which by reason of the peculiar construction and arrangement of its parts will be more compact in form or will occupy lessspace and will be of fewer pieces, less expensive, and much simpler or easier to manufacture and less liable to get out of order than most setting mechanisms of a like type heretofore in general use.

Another important object of the invention is to so construct the set that it may easily be applied to all American-style watches which employ clutch-wheels without altering the model.

A further object and advantage is to provide an improved pendent set which can be placed on either side of the clutch-wheel, thereby adapting it for use without alteration in either hunting-case or open-face watches.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1 'is a rear View in elevation of a Watch with the back of the casing removed, showing my improved pendent set and illustrating the parts in their normal or ordinary position. Fig. 21s a front view in elevation,

showing the parts in a like position. Fig. 3 is an enlarged view in elevation of the setting mechanism detached, showing by full lines the normal position of the parts and by broken lines the positions the parts will occupy when adjusted in setting the hands of the watch. Fig. a is a side view of the setting arm or lever. Fig. 5 is an inner edge view thereof, and Fig. 6 is a portion of the spring employed in actuating the mechanism.

Like numerals of reference refer to corresponding parts throughout the different views of the drawings.

The reference-numeral 10 represents the watchcasing, which is shown as being of the American style--that is, as having a pendent sleeve 11 on its periphery, through which extends a rotatable stem or arbor 12, which has fixed on its outer end a milled knob or thumbpiece 18, used for turning and moving said stem or arbor back and forth. That portion of the stem or arbor 12 which extends into the casing 10 is journalcd and longitudinally movable in bearings la and 15, suitably supported within the casing.

Rigidly mounted on the stem or arbor 12, within the casing 10, is a gear 16, which engages the winding mechanism, (not shown,) which may be of the ordinary or any preferred construction. The inner face of the gear 16 is provided with ratchet-teeth 17 to engage similar teeth 18 on the outer face of a clutch 19, which is movably mounted but non-rotatably secured on the stem 12 between its bearings 14 and 15, as is clearly shown in Fig. 1 of the drawings. The inner end of the clutch 19 is provided with teeth 20 to engage a gear 21 of the setting mechanism, which may be of the ordinary or any preferred construction. As shown in Figs. 1 to 3, inclusive, the clutch 19 is provided with an annular groove or channel 22, in which projects and operates the inner end of a vibrating lever 23, which is fulcrumed on a pin 24, located near one side of the stem or arbor. This vibrating lever has its outer portion curved, as at 25, and its outer end beveled, as at 26, for the purpose to be presently explained. The inner portion of the lever 23 is provided on its surface adjacent to the setting mechanism with a lug 27, with which one end of the actuating-spring 28 engages.

Fulcrumed on a pin or point 29, near the inner end of the stem 12 and on the same side thereof as the pin or point 29, is a setting-lever 30, the inner portion of which is formed with a recess 31 to provide an extension or foot 32, with whichthe inner end of the stem or arbor 12 engages. The outer portion of the setting-lever 30 is curved toward the vibrating lever, as at 33, and has its outer end beveled or rounded, as at 34, to coact with the beveled portion 26 of the vibrating lever. The inner surface of the outwardly-extending portion of thelever 30 is provided with a notch or recess 35 to receive the outer end of the spring 28, which is of considerable width, but quite thin, and possesses great resiliency. Each of the ends of the spring 28 is provided with prongs 36, those on the outer end of the spring being for the purpose of striding the outer end of the setting-lever 30, while those on the inner end of the spring are for the purpose of striding the lug or projection 27 on the vibrating lever. By thus forming the ends of the spring and by providing the said lug and the upper end of the setting-lever with recesses or notches 35 it is apparent that the spring will be securely held in position between said levers, thus preventing its accidental dislocation, besides eifecting a great saving in the space occupied by the mechanism.

From the foregoing and by reference to the drawings it will be seen and clearly understood that when the parts are in the position shown by continuous lines in Figs. 1, 2, and

.3, which are their normal or ordinary positions, the action of the spring 28 will be exerted against the lug 27 on the inner portion of the vibrating arm in such a way as to hold the outer face of the clutch 19 in engagement with the ratchet-teeth on the face of the wheel 16, which, as before stated, meshes with or engages the winding mechanism. When it is desired to set the hands of the watch, the stem 12 is pulled outwardly, thereby releasing its inner end from the foot or extension 32 of the setting-lever, which by reference to the drawings it will be seen has a greater leverage than the vibrating lever. In this operation the outer portion of the setting-lever will be forced outwardly by the spring 28, thus causing the rounded portion 34 of its outer end to coact with the beveled portion 26 of the vibrating lever, so as to cause the inner portion of the last-named lever to be moved toward the setting mechanism, thereby moving the clutch 19 on the stem out of engagement with the gear 16 and into engagement with one of the gears 21 of the setting mechanism, when by turning the stem 12 it is evident the hands may be properly set. l/Vhen in the position just above described, it is apparent that the clutch will be locked in engagement with the setting wheel or gear.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a stem winding and setting watch, the combination with the casing, of a winding mechanism and a setting mechanism, a rotatable and longitudinally movable stem, a clutch movable on said stem for engagement with said mechanisms, a vibrating lever having its inner end in engagement with the clutch and its outer portion curved and its free end beveled, a setting-lever adapted to engage at its inner portion the inner end of the stem and having its outer portion curved toward the outer portion of the vibrating lever, the end of the outer portion of the setting-lever being rounded to impinge the beveled end of the vibrating lever whereby the clutch is held in engagement with the setting-gear, and a spring embraced by said levers and having one of its ends secured to the outer portion of the setting-lever and its other end connected to the inner portion of the vibrating lever, substantially as described.

2. In a stem winding and setting watch, the combination with the casing, of a winding mechanism and a setting mechanism, a longitudinally-movable stem, a clutch movably mounted on the stem for engagement with said mechanisms, a vibrating lever having its inner end in engagement with the clutch, a setting-lever of greater leverage than the vibrating lever and adapted to engage at its inner portion the inner end of the stem, the outer portions of said levers being approximated and adapted to impinge and lock one another when the stem is moved outwardly whereby the clutch is held in engagement with the setting-gear, and a spring embraced by said levers and engaging at one of its ends the inner portion of the vibrating lever and at its other end the outward portion of the setting-lever, substantially as described.
